I'm not sure if I like this idea or not, but I can think of times when I 
'could' have used it.  I think I would probably still prefer to use 
multiple If/EndIf's instead though.  It is too easy to look at that code 
and not see that it could meet multiple conditions.  I would just take out 
that last When A = 5 or A = 7 or A = 8 and make that an IF statement after 
the EndSl.

I guess the way a Switch/Case statement works in C++ would be similiar to 
how I would use a Select/When in RPG.  If a variable is being tested for a 
different value, I would use a select. If I am testing multiple unrelated 
conditions I would use If/ElseIf.
